'11 Claims. Cl, 105-369) This invention relates, generally, to ladingtie anchors for railway cars and it has particular relation to suchanchors for gondola cars.

-Among the objects of this invention are: To provide for receivingeither lading tie rods or flexible lading ties in the form of straps atspaced locations along the top side chords of railway gondola cars; tospace the channels forming the top side chords and facilitate assemblythere of; to center and laterally support the lading tie rods whileproviding for the application of lading tie straps in the absence of therods; to employ a generally rectangular tubular member for the foregoingpurposes; to form the generally rectangular tubular member of twoidentical drop forgings; and to form the generally rectangular tubularmember of a one piece steel casting.

Other objects of this invention will, in part, be obvious and in partappear hereinafter.

This invention is disclosed in the embodiments thereof shown in theaccompanying drawings and it comprises the features of construction,combination or elements and arrangement of parts that will beexemplified in the con structions hereinafter set forth and the scope ofthe application of which will be indicated in the appended claims. i

For a more complete understanding of the nature and scope of thisinvention reference can be had to the following detailed description,taken together with the accompanying drawings in which:

Figure 1 is a topplan view of a portion of a top side chord of a railwaygondola car embodying the present invention;

Figure 2 is a vertical sectional view taken generally along the line 22of Figure -1;

Figure 3 is a vertical sectional view taken generally along the line 3-3of Figure 1;

Figure 4 is a view, in front elevation, of one of the drop forgings thatis employed to form the generally rectangular tube shown in Figures 1,2' and 3 of the drawings;

Figure 5 is a view partly in horizontal section and partly in top planand taken generally along the line 5-5 of Figure.4;

Figure 6 is a horizontal sectional view taken generally along the line6-6 of Figure 4;

Figure 7 is a vertical sectional view taken generally Figure 11 is avertical sectional view taken generally" along the line 11-11 of Figure10; and

Figure 12 is a horizontal sectional view taken general- 1y along theline 12-12 of Figure 10.

Referring now particularlyto Figures 1, 2 and 3 of the drawings, it willbe observed that the reference character 10 designates, generally, a topside chord for a railway gondola car. 'It is formed as a box likestructure by a lower channel member 11 and an upper channel member 12which preferably are formed of rolled structural steel shapes. The lowerchannel member 11 has upstanding side flanges 13 which interfit betweendepending side flanges 14 of the upper channel member '12. They aresecured inseparably together by welding as indicated at 15. 'While theflanges 13 are indicated as being telescoped' between the dependingflanges 14, it will be understood that the channel members 11 and 12 canbe of identical size'in which case the upper edges ofthe side flanges 13would register with the lower edges of the depending flanges 14.

The lower channel member 11 is welded at 16 and '17 to a car side plate18. Since the other portions of the car structure form no part of thepresent invention and since they are well understood in the art, furtherdescription of the car structure will not be set forth herein.

The present invention has to do particularly with the construction ofthe top side chord 10 so that it is capable of receiving various typesof lading ties. As presently constructed gondola cars are manufacturedto widths which just comply with maximum allowable clearance lines.Assuming that the top side chord 10 extends along the left side of agondola car, then the left side of the top chord 10 extends to the limitof the width which is permitted by regulations which provide for aminimum clearance between cars on adjacent tracks. There is then littleroom for the application of lading tie receiving means beyond the leftside of the top chord 10.

Because the gondola cars are used for handling various types of lading,it is desirable to provide for different types of lading ties. Inparticular it is desirable to provide for the application of flexiblelading tie straps as indicated e by broken lines at 21 in Figure 2.-Also it is desirable tie rod 22 having a circular cross section by thesame lading tie receiving means.

For this purpose the central portions 25 and 26 of the lower and upperchannel members 11 and 12 are provided with registering generallyrectangular openings 27 and 28. These openings can be formed by, asuitable punching operation. Interconnecting the registering rectangularopenings 27 and 28 is a generally rectangular tube that is indicated,generally, at '29. The tube 29, as

will appear presently, is arranged to receive either the flexibleladingtie strap 21 or the lading tie rod 22 of solid cross section.

pair of drop, forgings 30, one of which is shown in Figure 4, or, aswill appear hereinafter, it can be formed of a one piece steel casting.When it is formed of a pair of drop forgings 30, they are of identicalconstruction to reduce cost and facilitate assembly.

As illustrated in Figures 1 and 2 of the drawings, the lower and upperends of the generally rectangular tube 29 are welded as indicated at 31and 32 to the central portions 25 and 26 of the lower and upper channelmembers 11 and 12. Preferably the construction is such that the ends ofthe generally rectangular tube 29 do not project above or below theouter surfaces of the central portions 2's and 26 of the channel members11 and 12.

When the channel members 11 and 12 are assembled wood blocks. 1 Since nopractical way has been devised for removing the wood spacing blocksafter the channel been necessary to leave them in the assembly.

In accordance with the present invention the use of the wood spacingbloclgs can be avoided by the provision of shoulders 33 and 34 near theendsot the generally rec tangular tube 29. It will be observed thatthese shoulders engage the adjacent faces 35 and 360i thecentralportions 25 and 26 and thereby serve to space the channel members11 and 12 at the proper distance apart to permit the welding at 15 to becarried out. p L 1 With a view to accurately positioning the dropforgings 30 in a pair for forming the generally rectangular tube 29protuberances 37 and recesses'38 are provided in the juxtaposed edges.As shown in Figure 4 the protuberances 37 are located at the bottom'ofone of the forgings 30 and the recesses 38 are located at the top. Forthe mating forging 30, the same construction is used but it is turnedend for end so that the protuberances 37-will register with recesses 38.a v

The inner surfaces of the lower and upper ends of'the generallyrectangular tube 29 are rounded as indicated at 41 and 42 in order toavoid the presence of sharp edges which might abrade the flexible tiestrap 21 as will be understood readily. I

In order to provide for receiving the lading tie'rod 22 andsupportingthe same against lateral movement, ribs 43 are formedintegrally with the inner walls of the drop forgings 30. The midsections or central portions 44 of the ribs 43 provide a circularsection 45 of substantial length, as shown more clearly in Figures 1,4and of the drawings. Since the circular lading tie rod 22 extendsthrough this elongated circular section 45, it is guided thereby andheld against lateral movement. In order to provide for the ingress andegress of the flexible lading tie strap 21 in the absence of the ladingtie rod 22, the upper and lower ends of the ribs 43 are tapered asindicated at 46 from a maximum height at the mid sections 44 to aminimum at the lower and upper ends-of each drop forging 30.

It is desirable to provide a substantially uniform cross section for thedrop forging 30. Accordingly, as shown in Figure 9, grooves 47 areprovided in the side'opposite the side provided with the ribs 43.

Referring now particularly to Figures 10, 11 and 12 of the drawings, itwill be observed'that the generally rectangular tube 29, previouslyreferred to, is here shown as a one piece steel casting 50. Such aconstruction can be employed where greater strength is desired and wherethe additional cost of employing the casting process is warranted. Theconstruction otherwise is the same as for the generally rectangular tube29, previously described, and made up of two forgings 30.

In assembling the top side chord 10, the generally reo tangular tube 29constructed of two drop forgings 30 or the one piece casting 50 can beused. The required number of these rectangular tubes are assembled withthe lower and upper channel members 11 and 12 so that they are spacedapart by the shoulders 33 and 34 at the lower and upper ends, aspreviously described. .Then the' side flanges l3 and 14 can be weldedtogether as indicated at 15 and the ends of the generally rectangulartubes 29 can be welded as indicated at 31 and 32. A rigid constructionthen is provided and it is unnecessary to use the wood spacing blockspreviouslyrequired. The rectangular configuration of the tube 29 permitsthe application of a flexible lading tie strap 21. Since its thicknessis relatively small, it does not add substantially to the width of thecar. Alternatively the circular section 45 in each of the generallyrectangular tubes 29 is adapted to re-' oeive a lading tie rod 22 and tohold the same against lateral movement. 7

Since certain further changes can be made in the foregoing constructionand different: embodiments of the in- 4 and scope thereof, it isintended that all matter shown in the accompanying drawings anddescribedhereinbefore shall be interpreted as illustrative and not in a limitingsense.
